The display part 3 is rotated in an R1-R2 direction shown in FIG. 7 together with the supporting member 55 with respect to the supporting protrusions 13, 13, with the first supporting shaft 56 used as the center of rotation. The display part 3 is also rotated in an S1-S2 direction shown in FIG. 7 with respect to the supporting member 55 via the second supporting shaft 57.

Hereinafter, each use mode of the portable information processing device 1 will be described with reference to FIGS. 6 to 15. The portable information processing device 1 can be used as a video camera as well as a computer.

FIG. 6 shows a mode in which the portable information processing device 1 is not used as a computer or a video camera, with the keyboard 4 closed by the display part 3 (hereinafter referred to as “nonuse mode”). In the nonuse mode, the display part 3 closes the keyboard 4, with the display screen 46 facing the keyboard 4. The lock pawls protruding upward from the lock pawl insertion holes 10, 10 of the computer body 2 are engaged with the opening edges of the engagement holes 52,52 formed on the front side 47 a of the frame part 47 of the display part 3. The display part 3 is thus locked to the closing position.

If the power button 12 is operated to turn the power “ON” in the nonuse mode, the portable information processing device 1 can be immediately used as a computer or a video camera by rotating the display part 3.

FIG. 7 shows a mode in which the portable information processing device 1 is used mainly as a computer (hereinafter referred to as PC mode). The display part 3 is rotated from the closing position shown in FIG. 6 into the R1 direction shown in FIG. 7, thus opening the operation keys 5, 5, . . . of the keyboard 4 provided on the computer body 2. In this state, the user can operate the operation keys 5, the stick-type pointing device 6, the left click button 7, the right click button 8, the center button 9, the rotary dial 50 and the like so as to carry out input or editing of inputted information.

Even in the PC mode, the portable information processing device 1 can be used as a video camera by operating the rotary dial 50, the application button 36, the menu button 37, the A-button 38, the B-button 39 and the like. When using the portable information processing device 1 as a video camera, the user can turn the camera unit 40 to face a desired direction with respect to the computer body 2.

From the PC mode shown in FIG. 7, the display part 3 is rotated about the second supporting shaft 57 into the S1 direction or S2 direction shown in FIG. 7 (see FIG. 8). Then, the rotation is stopped when the display part 3 is turned 180 degrees to the computer body 2 (see FIG. 9). At this point, the display screen 46 of the display part 3 faces substantially backward, and a tripod shooting mode is set, in which the portable information processing device 1 is mainly used with a tripod. In the tripod shooting mode, the portable information processing device 1 is fixed to the tripod by using the tripod screw hole 27 formed in the bottom surface part 2 d of the computer body 2, and for example, fixed-point observation can be made. Meanwhile, in the tripod shooting mode with the display screen 46 of the display part 3 facing backward, for example, the portable information processing device 1 can be held by hands without fixing the computer body 2 to the tripod and thus can be used as a video camera.

In the tripod shooting mode, similarly to the PC mode, the camera unit 40 can be rotated to face a desired direction with respect to the computer body 2.

In the tripod shooting mode, the display part 3 is rotated about the first supporting shaft 56 and the operation keys 5 are closed by the display part 3, as shown in FIG. 10. In the state where the operation keys 5 are closed by the display part 3, as the slide knob 16 provided on the front side 2 b of the computer body 2 is slid leftward, as described above, the lock pawls protrude upward from the lock pawl insertion holes 10, 10 and are engaged with the engagement holes 54, 54, thus locking the display part 3 at the closing position. In this state, the display screen 46 faces outward.

The user holds the portable information processing device 1 so that the one end part 47 e of the frame part 47 is on the lower side while the other end part 47 c is on the upper side. The user holds both lateral edges of the portable information processing device 1 with his/her both hands and uses the camera unit 40 while looking forward, thus using the portable information processing device 1 as a video camera (see FIG. 11).

When shooting with the camera unit 40, the user can rotate the camera unit 40 so that the front lens 43 faces the opposite direction to the person who is shooting, and can shoot an object facing the person who is shooting (see FIG. 12). This use mode is an other-shooting mode mainly for shooting a facing object. The camera unit 40 can be rotated until its distal end is abutted against the button arrangement part 31 of the computer body 2. The maximum angle of rotation is 120 degrees, as shown in FIG. 13.

Moreover, when shooting with the camera unit 40, the user can rotate the camera unit 40 so that the front lens 43 faces the person who is shooting, and for example, the person who is shooting can shoot himself/herself (see FIG. 14). This use mode is a self-shooting mode mainly for shooting an object on the side of the person who is shooting. The camera unit 40 can be rotated until its distal end is abutted against the button arrangement part 31 of the computer body 2. The maximum angle of rotation is 120 degrees, as shown in FIG. 15. In the portable information processing device 1 according to the present invention, the camera unit 40 can be rotated within an angular range of 240 degrees (see FIGS. 13 and 15).

In the portable information processing device 1 according to the present invention, whether the direction of rotation of the camera unit 40 is inverted or not is detected when the camera unit 40 is rotated 15 degrees toward the person who is shooting from the center of the rotational range, as shown in FIG. 15, and an image displayed on the display screen 46 is inverted and an image in the correct up-and-down direction is displayed. The other-shooting mode is set when the camera unit 40 is rotated in the direction P shown in FIG. 15, and the self-shooting mode is set when the camera unit 40 is rotated in the direction Q shown in FIG. 15.

The use mode as a video camera using the camera unit 40 can also be used in a state in the process of setting each mode of FIG. 8 or the like, as well as the above-described PC mode, tripod shooting mode, other-shooting mode and self-shooting mode.

The circuit structure of the portable information processing device 1 will now be described (see FIG. 16).

A CPU 58 for generally controlling various functions is provided in the computer body 2. The CPU 58 is connected to a host bus 59. The processing in accordance with various programs and application software loaded in a RAM (random access memory) 60 by the CPU 58 is executed at a predetermined operation speed on the basis of a system clock provided from a clock generator 61, thereby carrying out various functions.

A cache memory 62 is connected to the host bus 59. Data to be used by the CPU 58 is cached by the cache memory 62, thus carrying out high-speed access.

The host bus 59 is connected to a PCI (Peripheral Component Interconnect) bus 63 via a host PCI bridge 64. The host PCI bridge 64 is connected to the RAM 60 via a memory bus 65. The PCI bus 63 is connected with a video controller 66, an IEEE 1394 interface 67, a video capture processing chip 68, and a PC card interface 69. The host PCI bridge 64 controls transmission and reception of various data between the CPU 58 and the video controller 66, IEEE 1394 interface 67, video capture processing chip 68 or PC card interface 69, and also carries out memory control of the RAM 60 connected thereto via the memory bus 65. Moreover, the host PCI bridge 64 is connected with the video controller 66 via a signal line along an AGP (accelerated graphics port) 70, thus transferring image data between the host PCI bridge 64 and the video controller 66 at a high speed.

The video capture processing chip 68 is connected with an SM (system management) bus 71, which is a serial bus. When image data shot by the camera unit 40 is supplied to the video capture processing chip 68 via the SM bus 71, the supplied image data is temporarily stored into a frame memory, not shown, embedded in the video capture processing chip 68. Then, image compression processing is performed in conformity with the JPEG (Joint Photographic Experts Group) standard, thus generating JPEG image data. The resultant JPEG image data is again stored into the frame memory. The video capture processing chip 68 transfers the JPEG image data stored in the frame memory to the RAM 60 by using a bus master function in accordance with a command signal sent from the CPU 58, and transfers the image data to an HDD (hard disk drive) 72 as JPEG image data (static image data) or motion JPEG image data (dynamic image data).

The video controller 66 performs predetermined graphics processing on the image data shot by the camera unit 40 or the JPEG image data generated by the video capture processing chip 68, then stores the image data into a VRAM (video random access memory) embedded therein, not shown, then suitably reads out the image data, and displays the image on the display screen 46 having the LCD. The video controller 66 also outputs to the display screen 46 image data based on various application software supplied thereto and displays a plurality of window screens.

The PC card interface 69 is connected to the PC card slot 26, and is mounted via a PC card when adding an optional function. For example, the PC card interface 69 is connected to an external device such as a CD-ROM drive or DVD drive via a PC card.

The IEEE 1394 interface 67 is connected with the IEEE 1394 terminal 33. For example, the IEEE 1394 interface 67 is connected to an external device such as another computer unit or digital video camera via the IEEE 1394 terminal 33.

The PCI bus 63 is connected with an ISA bus 74 via a PCI-ISA (Industrial Standard Architecture) bridge 73. The HDD 72 and the USB terminal 25 are separately connected to the PCI-ISA bridge 73. The PCI-ISA bridge 73 is constituted by an IDE (Integrated Device Electronics) interface, a configuration register, an RTC (real time clock) circuit, a USB interface and the like. The PCI-ISA bridge 73 controls the HDD 72 via the IDE interface on the basis of the system clock provided from the clock generator 61.

On the hard disk of the HDD 72, an OS (operating system), an e-mail program, an autopilot program as well as various application software is stored, and such application software or the like is transferred to the RAM 60 in the process of start-up processing. The PCI-ISA bridge 73 controls, via the USB interface, external devices such as a floppy disk drive, a printer and a USB mouse connected thereto via the USB terminal 25, and also controls a modem 75 and a sound controller 76 connected to the ISA bus 74. The modem 75 is connected to the modem terminal 22. The sound controller 76 is separately connected to the stereo speakers 18, 32 and the stereo microphone 53 via multiplexers 77, 77 and an audio codec 78. A predetermined command signal is sent to the audio codec 78 from an I/O controller 79 via the ISA bus 74.

The modem 75 is connected with an Internet service provider via the modem terminal 22 and a telephone line or the Internet. The sound controller 76 carries out intake of an audio signal through the stereo microphone 53 and output of an audio signal to the stereo speakers 18, 32.

The ISA bus 74 is connected with the I/O controller 79 and is supplied with power from an external power connector 81 via a power-supply charge control circuit 80. When the power button 12 is “ON”, the power is supplied to each part. The I/O controller 79 is connected with the clock generator 61 and operates on the basis of the system clock supplied from the clock generator 61. The power-supply charge control circuit 80 is controlled by the I/O controller 79 and controls the charging of the battery of the battery pack 29.

The I/O controller 79 is constituted by a microcontroller, an I/O interface, a CPU, a ROM, a RAM and the like. The I/O controller 79 controls input/output of data between the OS and application, and the peripheral equipments such as the display screen 46 and the HDD 72, on the basis of BIOS (basic input output system) stored in a flash memory 82.

The I/O controller 79 is connected with an inverting switch 83. The inverting switch 83 includes a lid switch 83 a for detecting the rotating state of the display part 3 when the display part 3 is rotated in the R1-R2 direction shown in FIG. 7 to open/close the keyboard 4, an LCD switch 83 b for detecting the rotating state of the display part 3 when the display part 3 is rotated in the S1-S2 direction shown in FIG. 7, and a camera switch 83 c for detecting the rotating state of the camera unit 40 when the camera unit 40 is rotated with respect to the computer body 2. The lid switch 83 a is provided, for example, at the rear end of the upper surface part 2 a of the computer body 2. The LCD switch 83 b is provided, for example, on the second supporting shaft 57. The camera switch 83 c is provided, for example, on the shaft which supports the camera unit 40 on the computer body 2.

The I/O controller 79 is also connected with the capture button 48. When the capture button 48 is half-pressed or fully pressed as described above, a signal to that effect is inputted to the CPU 58 and a predetermined mode is set.

Specifically, if the capture button 48 is half-pressed when predetermined software for image pickup is being transferred from the hard disk of the HDD 72 to the RAM 60, the static image mode is set and a static image is frozen. If the capture button 48 is fully pressed, the frozen static image data is taken in and sent to the video controller 66. Then, as the capture button 48 is half-pressed, the focusing adjustment is carried out as described above. The focusing adjustment can also be carried out by a manual operation of rotating the focusing ring 42 of the camera unit 40.

On the other hand, if the capture button 48 is fully pressed when predetermined software for image pickup is not being transferred to the RAM 60, the dynamic image mode is set and dynamic image data is taken in and sent to the video controller 66.

In the ROM of the I/O controller 79, various programs are stored such as a rotary dial monitor program, a key input monitor program and an indicator control program. The rotary dial monitor program is a program for monitoring the states of the rotating operation and pressing operation of the rotary dial 50. The key input monitor program is a program for monitoring the input of the operation keys 5, the stick-type pointing device 6, the left click button 7, the right click button 8, the center button 9 and the like. The indicator control program is a program for controlling turning on/off of the indicators 11 and the indicators 14.

When the display part 3 is not rotated in the S1-S2 direction shown in FIG. 7 and the display screen 46 faces forward, the LCD switch 83 b is “OFF”. As the display part 3 is rotated in the S1-S2 direction, the LCD switch 83 b is made “ON”. Therefore, the LCD switch 83 b is “OFF” in the nonuse mode and the PC mode, and “ON” in the tripod shooting mode, the other-shooting mode and the self-shooting mode.

When the camera unit 40 is at a position rotated in the direction P shown in FIG. 15, the camera switch 83 c is “OFF”. When the camera unit 40 is at a position rotated in the direction Q shown in FIG. 15, the camera switch 83 c is “ON”. Therefore, the camera switch 83 c is “ON” or “OFF” in the nonuse mode, the PC mode and the tripod shooting mode, and “OFF” in the other-shooting mode, and “ON” in the self-shooting mode.

When shooting is carried out by the camera unit 40, the shot data is sent to the video controller 66 as “normal image” data or “vertical and horizontal inversion” data by detecting the states of the lid switch 83 a and the camera switch 83 c. In this case, whether the lid switch 83 a is “ON” or “OFF” is detected. If the lid switch 83 a is “OFF”, the data is “normal image” data. If the lid switch 83 a is “ON”, the result of detection of the camera switch 83 c is referred to. If the camera switch 83 c is “OFF”, the data is “normal image” data. If the camera switch 83 c is “ON”, the data is “vertical and horizontal inversion” data. The “normal image” or “vertical and horizontal inversion” data is sent to a recording means such as a hard disk from the video controller 66 and recorded to the recording means on the basis of the operation to the capture button 48.

An image is shown in a preview on the display screen 46 on the basis of the data outputted from the camera unit 40. The image shown in the preview is the data processed on the basis of predetermined bus setting (hereinafter referred to as “preview setting”).

The preview setting is carried out by detecting the respective states of the lid switch 83 a, the LCD switch 83 b and the camera switch 83 c. If the LCD switch 83 b is “OFF”, the data outputted from the camera unit 40 is set to be “horizontally inverted”. If the LCD switch 83 b is “ON” and both the lid switch 83 a and the camera switch 83 c are “ON”, the data is set to be “horizontally inverted”. If at least one of the lid switch 83 a and the camera switch 83 c is “OFF”, the data outputted from the camera unit 40 is set to be shown as it is in real time in the preview. Therefore, in the tripod shooting mode and the other-shooting mode, an image shown in the preview is a “normal image”. In the PC mode and the self-shooting mode, an image shown in the preview is a “horizontally inverted” image.

As described above, since in the tripod shooting mode and the other-shooting mode, an image shown in the preview is a “normal image”, while in the PC mode and the self-shooting mode, an image shown in the preview is a “horizontally inverted” image, images of natural forms with no uncomfortable feeling is constantly provided to the user.
